LUMBER-DRIER.

SPECIFICATION forming part of Letters Patent No. 473,116, dated April 19, 1892.

Application filed June 6, 1891. Serial ITO-395,288. No model.)

To aZZ whom it may concern: is located below the level of the furnace-floor.

Be it known that I, J OHN. O. HAY, a citizen By this arrangementall the smoke and sparks of theUnited States,residing at Kinston,in the which issue from the furnace are turned county of Lenoir and State of North Carolina,: down by the deflector D into the water in the 5 haveinventedcertainnewandusefulImprovereceptacle E and the smoke passes upward ments in Lumber-Driers; and I do hereby dc and out of the stack. Thus the danger of clare the following to be a full, clear, and exsparks passing out of the stack and setting act description of the invention, such as will fire to the drying-house or other structure is enable others skilled in the art to which it completely obviated, and at the same time x0 appertains to make and use the same. ,7 the volume of smoke is greatly diminished.

My invention relates to improvements in The furnace B is provided with a metallic lumber-driers; and the object is to provide a top piece 6, which extends rearwardly from simple and easily-constructed drying-house the furnace through the structure and across in which lumber or tobacco can be dried by the top of the smoke-stack base 0, and the 15 heat generated in a furnace which is located smoke-stack O is built on this base in amanbeneath the same. ner well known in the art.

A through the openings g and then upward metallic front piece a is secured on the front and through the lumber. This is advan- 0 of the furnace to close all the openings, and tageous and desirable, because the top of the said front piece is provided with a door a, furnace, if in contact with the lumber, would through which fuelis adapted to be fed to the be liable to set fire thereto or injure it in furnace. The base 0 of the smoke-stack 0 other ways; but by providing the equalizingis arranged directly in rear of the furnace chamber above the furnace this danger is 5 5 B, and the furnace-chamber opens directly avoided. Around the edges of the metallic into the base 0. A deflector D is secured at plate G is a layer of bricks or other refracthe upper juncture of the base 0 with the tory material 0, and the Ways h are arranged furnace proper, and it extends downwardly thereon, as shown in Figs.

The across the stack-opening toward the door 0. lumber is piled on a movable rectangular I00 50 A water-receptacle E is secured in the botframe of a truck H, which is run into the tom of the base 0 of the smoke-stack, and it drying-house through an opening inone side thereof on the ways it, secured on the ends of the structure. The opening in the side of the drying-house is adapted to be closed by suitable doors I, which are arranged to slide in the ways '5 in a frame 1'', secured on the side of the drying-house, and this frame projects beyond the ends of the house a short distance to permit the doors to be run back in the Ways and leave the opening entirely unobstructed, so that the truck H, carrying the lumber, can be removed. A safety-valve J is provided on the top of the drier to allow the steam to escape when it accumulates in the dlying-chamber.

It is obvious that my improved dryinghouse can be used for many other purposes than drying lumber-as, for instance, drying tobacco--and I can also connect the structure with a dwelling by means of pipes to heat the latter, if desired.

One of the principal advantages of this structure is that it will dry the lumber by hot-air and not by smoke, as is usually the vase, and thus the life of the lumber is not destroyed; but the lumber when dressed will present a glossy appearance and be easy to work; also, if the drying-house should accidentally be set on fire on the interior thereof the smoke will put the fire out, as the house is practically air-tight.

I am aware that changes in the form and construction and arrangement of parts can be made Without departing from the spirit or sacrificing the advantages of my invention, and I therefore reserve the right to make such changes as fairly fall Within the scope of my invention.

Having thus fully described my invention, What I claim as new, and desire to secure by Letters Patent, is-

In a lumbendrier, the fnrnace-chan1ber B, a drying-chamber A, the metallic plate I), arranged above the furnace, a layer 9 of refractory material around the edges of said plate, the blocks g of refractory material, arranged at intervals on said layer to leave the openings g another metallic plate G, placed on the blocks 9 and forming with the plate Z) a heat-equalizing chamber between them, and a layer 0 on the top of the plate G to receive the Ways h and prevent them from contacting with said plate, substantially as described.

In testimony whereof I allix my siguatu rein presence of two witnesses.
